From 2001-2004, Ms. Edgerton practiced in Los Angeles, where her caseload emphasized environmental law, toxic torts, litigation pursuant to California's Proposition 65, also know as the California Safe Drinking Water and Toxic Enforcement Act of 1986. Admitted in the 1980s to practice in the United States Supreme Court, Ms. Edgerton also enjoys writing, lecturing and making presentations at symposia, both domestically and internationally.

In 1993, California Governor Pete Wilson appointed Ms. Edgerton as the law member of the California Environmental Protection Agency's Air Resources Board. She served on the Cal/EPA Air Resources Board until 1999, during almost six-years of tremendous environmental protection gains for California.

In 1989, she was one of three attorneys who founded the Los Angeles Office of the Natural Resources Defense Council (NRDC), a public interest law and science firm that has been successful in forcing the partial clean up of California's air, water, and soil. From 1983 to 1989, Ms. Edgerton served as a staff attorney in the New York City office of NRDC.

In addition, Ms. Edgerton has served on various public service boards, including those that follow:

• Policy Advisory Committee of the California Environmental Technology Partnership
• Board of the Environmental Law Institute
• Board of the Climate Institute
• Board of Green Seal, Inc.
• Board of Population Action International, Inc.
• Mothers and Others for a Livable Planet, Inc.
• Dinner Committee, Covernant House Los Angeles Annual Gala
• Board, The Adirondack Council
• Board, Manitoga Conservancy
• Editorial Board, The Environmental Law Forum

During her almost six years as a voting member of the California Environmental Protection Agency's Air Resources Board, Ms. Edgerton became known as an aggressive advocate for simultaneous environmental and economic progress. During her service on the Cal/EPA Air Resources Board, globally pace-setting programs were adopted and implemented, including the following highlights:

• Successful introduction of the world's cleanest blend of commercially available gasolines and diesel fuels;
• Introduction and development of a consumer-oriented zero-emission vehicle program that stimulated tremendous clean car innovations, including low-polluting and zero-polluting vehicles such as hybrid-electric, fuel-cell electric and battery-powered electric vehicles;
• Timely adoption, for the first time in California history, of a California Clean Air State Implementation Plan ( 'SIP') that met the standards established in the federal Clean Air Act, and that the United States Environmental Protection Agency subsequently approved as compliant with the federal Clean Air Act;
• Adoption of California's Low Emission Vehicle Program II ( 'LEV II') for 2004-2010, which for the first time in history mandates that sports utility vehicles, or SUVs, and diesel passenger vehicles must meet the same stringent emission controls that traditional passenger cars running on California clean fuels must meet;
• Successful negotiation with the USEPA resulting in the subsequent adoption of national low emission vehicle standards similar in many respects to California's pace-setting clean car/clean fuel regulations;
• Successful adoption of a first phase program to reduce air and dust pollution in the Owens Valley that did not unduly impair Los Angeles' drinking water supply.

• An early expert in climate change, in 1991, Lynne wrote and published The Rising Tide: Global Warming and Sea Level Rise , a book outlining proactive steps that many policy-makers and educators have found useful in learning about and preparing for threatened accelerated sea level rise from global warming.

Lynne passed her first bar exam in 1972 and can practice in the following four states: CA, NY, VA and TN.
